CARPET-CLEANER.

iniaasia,

To all whom it may concern:

Be it known that l, Enno J. TANGEMAN, a citizen of the United States,and residing at Keystone, in the county of Benton and State of Iowa,have invented certain new and useful' Improvements in Carpet-Cleaners,of which the following is a specification.

This invention relates to certain new and useful improvements in carpetcleaners.

The present'invention is an improvement upon the carpet cleaner shown,described, and claimed in the patent issued to me, @ctober 22, 1912,#1,0&2,05l.

The present inventionhas for its object to provide in connection with acarpet cleaner of the type shown, described and ,claimed in theabove-mentioned patent, ,a suction device interposed between the beatersand the napmestoring brush of the cleaner whereby to efiectually removeany dust remaining in the carpet after the latter has been acted upon bythe heaters.

The invention has for its further object to provide a carpet cleaner ofthe type shown in said patent, with a suction device so arranged thatthe same may be cut out of operation and the cleaner operated withoutthe suction device if desired.

A further object of my invention is to provide in a carpet cleaner ofthis type, a

suction device so arranged that a portion or carpets of various widthspassing through the cleaning machine.

With the above and other objects in view, the invention resides in thenovel construction, combination and arrangement of parts.

as will be hereinafter more fully described and then particularlyclaimed, and in describing the invention in detail, reference will be.had to' the accompanying drawings illustrating an embodiment of myinvention as it has been practised by me, like numerals of referenceindicating like parts throughout the different views in which Figure 1is a transverse vertical sectional view of a carpet cleaner inaccordance with my present invention.

In Patent #1,04,-2,054c above referred to, there is shown asuitable-supporting frame such as is designated 5 in the presentapplione of the shut-ofis and guides in sec- Patented Feb, 23, 1915.

cation. There is shown a carrying roll such as 6 in the presentapplication upon which the carpet as 7 is placed and from which itunwinds as' it passes through the machine. There is shown a heater shaftas 8 in the present application which carries a plurality of tappets foractuating heaters as 9 in the present application which strike upon thecarpet to dislodge the dust therefrom, the

dust or other foreign matter filtering through a screen as 10 into adust-collecting receptacle as 11 from where it is removed by a suitablesuction device as12. The de vice of saidpatent' also embodies areceiving roll as 14 in the present case, and a naprestoring brush as 15in the present case. The heater shaft in the device shown in the patentabove referred to is suitably driven,

and the nap-restoring brush is driven in unison therewith by a belt orother suitable form of gearing.

In the present invention, I employ in connection with the elements abovenoted, and which comprise a complete carpet cleaning machine, a suctiondevice over which the carpet is passed after it leaves the heaters andbefore it reaches the nap-restoring brush, which acts to extract anydust that may remain in the carpet after the same passes the heaters.

The said suction device comprises a. suction pipe 16 which extendsthroughout the length of the machine, and is disposed between thebeaters 9 and the nap-restoring brush 15, so that the carpet 7 must passthereover as it is unwound from the roll'6 and wound upon the roll 14.This suction pipe 16 is closed at its ends in any suitable manner as byplugs 17, and is provided on its upper face with a length-wise extendingslot 18 which of course terminates short of the extreme ends of the pipe16. Connected with said suction pipe, preferably at the lower sidethereof, are a series of upright pipes 19, which at their lower endsoinwith a receiving pipe 20, and in each of which pipes 19 there islocated a shut-0E valve 21. The pipe 20 is closed at its ends, and hascommunicating therewith, at any .desired point, but preferably at orabout mid-way;

thereof, a take-0d pipe 22, which has connection at its other end withpump cylinders- 23. Said pump cylinders 23 have discharge pipes 24leading into a common discharge 25. These cylinders 23 aresuitably-mounted at one end of the machine, toward the forward sidethereof, and the pistons (not shown) of said cylinders have their rods26 pivotally-comiected as at 26 to an arm 27 which is pivotally-mountedas at 27 on a bracket 28 carried by the frame 5 of the carpet beater. Alink 29 is connected at one end with a crank 30 at the end of the beatershaft 8 and at its other end to the arm 27 as at 29 so that as saidbeater shaft 8 is rotated, the oscillation imparted to the arm 27 willreciprocate the piston rods 26 and create a suction in the cylinders 23.

in order that the suction device may be cut out of operation and thebeater alone operated to clean the carpet, 1 preferably provide a clutch31 on the beater shaft which may be thrown into or out of engagement inany desirable manner as by the lever 32.

As in my prior patent above referred to, the beater shaft 8 carries apulley wheel 33 over which passes a belt 34, which engages a ulley onthe shaft of the nap-restoring rush 15, so that the latter will bedriven as the beater shaft is driven. The beater shaft has a drivepulley 35 over which passes the drive belt 36, it being preferable toprovide a tightening pulley 37 herein shown as adjustably mounted on astandard 38 which also carries the idler 39.

In order to adjust the length of the slot 18 to the width of the carpetbeing passed over the suction pipe 16, 1 provide in the latter a pair ofslide cut-offs 40 suitably packed as shown in Fig. so as to prevent airpassing between them and the inner wall of the pipe, and which haveprojections 41 extending through the slot 18 of the pipe 16. These slidecut-offs act as guides for the edges of the carpet, and may be adjustedas shown in Fig. 2 so as to out 0d the ends of the slot 18, the pipes 19which communicate with such cut-off ends of the pipe 16 being cut out bymeans of closing the valves 21.

In practice it will be understood that the cylinders 23, or the pipes22, 24, or both, are provided with suitable intake and exit valves sothat the dust when expelled through pipes 24 will not be again drawn Iinto the cylinders 23.

By providing the suction device, any dust which may remain in the carpetafter having been effectually loosened by the action of the heaters 9will be drawn into the suction pipe 16, from thence through the pipes19, 20, 22, into the suction cylinders 23, and expelled through pipes24, 25, the brush 15 acting to restore the nap to the carpet in the samemanner as was accomplished by the device shown in my prior patent abovereferred to.

Having thus fully described my invention, what 1 claim as new and desireto secure by Letters Patent of the United States is 1, In a carpetcleaner, a frame, a beater section, a nap restoring brush, and a suctiondevice disposed between the beater section and brush, said suctiondevice comprising a suction pipe closed at its bottom and slotted in itsupper face for the major portion of its length, combined guides and shutoffs in said pipe, carrying projections extending through the slot bywhich the same may be manipulated for varying the length of said slot, aplurality of down pipes connected with the suction pipe and eachprovided with a shut off valve, a receiving pipe to which the down pipesare connected, a take-0E pipe connected to said receiving pipe, andsuction creating means to which the takeoff pipe is connected.

2. In a carpet cleaner, a suction device comprising a suction pipeclosed at the bottom and slotted in its upper face, combined guides andshut offs in said pipe carrying projections extending through the slotby which the same may be manipulated for varying the length of suctionof said slot, a

plurality of down-pipes connected with the suction pipe and eachprovided with a shutoff valve, a receiving pipe to which the down.-pipes are connected, :1 take-off pipe connected to said receiving pipe,and suction-creating means to which the take-oh pipe is connected.

In testimony whereof I aflix my signature in presence of two witnesses.
